Endurakote® allows designers to take advantage of the cost savings of specifying stock bearings instead of more exotic materials. The coating can be applied to any type of bearing and to most bearing materials, including most ferrous and nonferrous metal. This is particularly beneficial for larger diameter bearings or where quick delivery is critical.
Endurakote® plating is effective in increasing wear resistance in sliding surface contacts. The micro-surface composition of Endurakote® plating aids in lubricant dispersion, enhancing base metals by reducing or eliminating galling, seizing, and high friction, over a wide range of installations and environments.
Endurakote® plating creates a buildup of less than 0.0002" under normal circumstances, and is compatible with most ferrous and nonferrous metal, allowing maximum flexibility in the selection of base material. Endurakote® plating is normally a final process, and its quality is constant with any given base metal, ensuring design reproducibility.
Properties and characteristics
Kaydon's proprietary Endurakote® hard chromium plating provides stock-material thin section and slewing ring bearings with excellent corrosion resistance and other benefits. Endurakote® properties and characteristics have been extensively tested.
Coefficient of friction
Effect on base
Endurakote® plating greatly enhances the base material, even when porosity of the base metal, compound concentration, and exposure time to the compound affect corrosion. In severe salt spray tests as well as tap water immersion tests, AISI 52100 steel with Endurakote® plating proved equal to fully hardened AISI 440C stainless steel in resistance to rusting. In many instances, Endurakote® plating provides better corrosion protection than cadmium plate, zinc plate, phosphates, chromates, black oxide or normal chrome plate. We invite inquiries about and will be pleased to arrange qualification tests of the coating.
Endurakote® plating has a matte or micro-orange peel surface with very good lubricant retention qualities.
